<H2>2. Supported CLHEP version</H2>

This release of Geant4 has been verified with
<A TARGET="ext" HREF="http://cern.ch/clhep/">CLHEP</A>, release <B>2.1.1.0</B>.
Use of a different CLHEP version may cause incorrect simulation results.

<!-- ============================================== -->

<H2>3. Items for migration of the user code</H2>

Listed here is some relevant information on developments included in this
release, some of which may require migrations (mainly for users of advanced
Geant4 features) in order to upgrade from release 9.4 to release 9.5.
Note that for all users a full re-installation of libraries (or a full
recompilation) and a recompilation of user applications is required.


<P> </P>
<B>Configuration</B>
<P> </P>
<UL>
<LI>The CMake system for installation replaces the old Configure script. 
    CMAKE has been extended to cover all features. 
    Complete information on how to use the new CMake system can be found
    in the User Installation Guide (Note: the old Configure script has been
    removed, as planned).</LI>
<LI>Geant4 now comes with an embedded CLHEP module (based for this release on
    version 2.1.1.0 of CLHEP), which includes the subset of CLHEP library
    classes required by Geant4. On installation there is a choice between using 
    this embedded module or installing CLHEP as an external library.
    Through the GNUMake system, the use/installation of the external CLHEP
    is triggered if the environment variable <TT>CLHEP_BASE_DIR</TT> is set;
    otherwise the embedded CLHEP module is used. 
    With the CMake system, the embedded CLHEP is selected by default.</LI>
<LI>An additional package, <TT>expat</TT>, required by the the new hadronic
    <TT>lend</TT> module is also included in the <TT>externals</TT> directory and is
    built automatically on Windows. On Linux or Mac, the <TT>expat</TT>
    library available in the system is used instead by default.</LI> 
</UL>

<P> </P>
<B>Standard Electromagnetic physics</B>
<P> </P>
<UL>
<LI>Standard EM physics lists now require the G4EMLOW data files (version 6.23), in order 
    to access precise cross-sections for Bremsstrahlung.</LI> 
</UL>

<P> </P>
<B>Low Energy Electromagnetic physics</B>
<P> </P>
<UL>
<LI>All classes describing interactions of electrons, positrons and photons
    (Livermore and Penelope based) have been upgraded to the common software
    design adopted by both Standard and Low-Energy electromagnetic domains.
    Users are invited to use these upgraded classes following the migration
    procedure described in the following page:
    <A HREF="https://twiki.cern.ch/twiki/bin/view/Geant4/LoweMigration">https://twiki.cern.ch/twiki/bin/view/Geant4/LoweMigration</A>.
    The old obsolete classes have been removed from the Geant4 kernel.
    Users are invited to contact the Low Energy Electromagnetic working group
    in case of difficulties with this upgrade.</LI>
</UL>

<P> </P>
<B>Persistency</B>
<P> </P>
<UL>
<LI>A new version of the GDML schema (GDML-3.0.1) is included in this
    release. The GDML reader and writer are now compliant with
    <A HREF="http://cern.ch/gdml/">GDML-3.0.1</A>.</LI>
<LI></LI> 
</UL>

<P> </P>
<B>Physics Lists</B>
<P> </P>
<UL>
<LI>Number of reference physics lists is reduced. Nearly all EM 'variant' physics 
    lists are no longer available as a class
    in the library (e.g., FTFP_BERT corresponds to a class in the library,
    FTFP_BERT_EMV does not exist as a class). However, EM options are all easily available from 
    updated <TT>G4PhysListFactory</TT>, allowing to use any EM option on top of a
    base hadronic physics configuration (e.g., it is possible to request "FTFP_BERT_EMV" by name).</LI> 
<LI>The implementation of physics-list constructors (builders) has been revised.
    Ordering numbers for processes are no longer used. Old method is still allowed but 
    it is recommended for a custom user's
    physics list to be revised to be compatible with the new mechanism.</LI>
</UL>

<P> </P>
<B>Use of Exceptions</B>
<P> </P>
<UL>
<LI>Obsolete signature of <TT>G4Exception</TT> (using only one, text string,
    argument) has been removed. Use of a signature with four arguments,
    including severity, is now mandatory.
    For code that is portable between previous releases and this release,
    it is necessary now to use the signature:
    <BR>
    <TT>void G4Exception(const char* issure, const char* errorCode, G4ExceptionSeverity severity, const char* comments)</TT>
    <BR>
    Note: the <TT>enum G4ExceptionSeverity</TT> has been defined since Geant4
          release 5.0 and its values are:
    <TT>FatalException, FatalErrorInArgument, EventMustBeAborted,
        RunMustBeAborted,</TT> and <TT>JustWarning</TT>. 
</LI>
</UL>

<P> </P>
<B>Data Sets</B>
<P> </P>
This release introduces new data set versions.
Please see the corresponding details in
<A href="#data-notes">Section 10</A> of this document.
<UL>
<LI>New data set versions: <TT>G4EMLOW.6.23, G4RadioactiveDecay.3.4,
    G4PhotonEvaporation.2.2, G4PII-1.3, G4NDL.4.0, G4NEUTRONXS-1.1</TT>.</LI>

<H2>4. New Developments and Capabilities </H2>

<B>Geometry</B>
<UL>
<LI>It is now possible to define volumes with material in 
    parallel geometry layers. 
    The volumes created can complement or overlap the standard 'main' geometry for tracking.  
    This new capability is called a "layered mass geometry".
    Zero, one or more additional layers for the mass geometry can be used.
    This is an enhancement of the existing functionality for parallel
    specialised geometries, which has been used for scoring, fast simulation, 
    shower parameterisation and event biasing.   
    The registered parallel geometries are scanned now for material.
    A side effect of this new capability is that all geometries and all regions 
    in the each world defined are now scanned for their material.</LI>
</UL>

<B>Materials</B>
<UL>
<LI>Applications with many materials can reduce their memory footprint 
    by using the new <TT>Base Material</TT> capability.
    With it, materials with the same composition but different density 
    will share entries in the tables of all electromagnetic processes.
    Tables with cross-sections, stopping
    powers and ranges are precomputed only for base materials.
    Any number of materials with different names and densities can be built from
    one base material.
    So, for example,it is now possible to define large number of "water" materials 
    with slightly different densities. Only the base "G4_WATER" physics tables
    will be built at initialisation; these will be scaled at run time for all
    derived materials .</LI>
</UL>

<B>Standard Electromagnetic physics</B>
<UL>
<LI>A new tune of the Urban multiple-scattering model for electrons is
    provided. Is is named <TT>G4UrbanMscModel95</TT>. This features
    higher accuracy of electron scattering and stability of energy 
    deposition when the step size is varied. The model is currently set as
    the default for electrons and positrons.</LI>
<LI>A new model for Bremsstrahlung, <TT>G4SeltzerBergerModel</TT>, is now
    used by default at energies below <TT>1 GeV</TT>. The model is based on
    tabulated cross-sections published by S.M. Seltzer and M.J. Berger.
    It provides agreement with the low energy Livermore and Penelope models
    below <TT>10 MeV</TT> and the standard relativistic model at <TT>1 GeV</TT>,
    improving the most over the previous 'standard' Bremsstrahlung model
    in the energy range from <TT>1 keV</TT> to <TT>1 GeV</TT>.</LI>
<LI>New biasing options are provided which can be used both with standard
    and low-energy electromagnetic physics. They include cross-section biasing,
    forced interaction, and secondary particle biasing. The secondary particle
    biasing consists of Bremsstrahlung splitting and Russian Roulette. All
    these options can be activated per process, particle, energy and
    geometrical region via UI commands or C++ code. </LI>
</UL>

<B>Hadronic physics</B>
<UL>
<LI>Interactions of antibaryons (including antihyperons) and light antinuclei with
    matter have been implemented in the Fritiof (FTF) model.  This model is valid
    for incident antibaryon energies from <TT>0 to 1 TeV</TT>, and for incident
    antinucleus momenta from <TT>150 MeV/c/nucleon</TT> up to <TT>2 GeV/c/nucleon</TT>.
    Corresponding antibaryon and antinuclear cross section classes have also been
    added. New processes were added to handle inelastic reactions of antideuterons,
    antitritons, anti3He and antialphas.</LI>
<LI>Cascade models
  <UL>
    <LI> Bertini
      <UL>
        <LI>The Bertini cascade is interfaced to the pre-compound and de-excitation 
            module, enabling improved generation of low energy secondaries. This
            option is fully benchmarked, and is targetted for applications sensitive
            to the spectra of low energy nuclear products.
        <LI>An interface for re-scattering the fragments of the high energy 
            string models has been created.  This is an early stage development. 
        <LI>Bug fixes in the three-body final state reactions provided slightly
            better angular distributions of final state hadrons.</LI>  
        <LI>Memory churn (allocation and de-allocation of memory) was significantly
            reduced throughout the model.</LI>
        <LI>A new nucleon-coalescence model is available, for improved production 
            of energetic deuterons and light ions. It is not the default 
            in existing configurations, due to the extra CPU cost.</LI>
        <LI>Gamma-nucleon channels were added for future use, but are not activated.</LI>
      </UL></LI>
    <LI> Binary
      <UL>
        <LI>The excitation energy used for re-scattering was improved.</LI>
        <LI>The large energy non-conservation observed for hydrogen targets was fixed.</LI>
      </UL></LI>
    <LI> INCL/ABLA
      <UL>
        <LI>The first version of INCL++, based on the INCL4.6 model, was released.
            It supports proton, neutron and pion projectiles up to <TT>3 GeV</TT>
            and uses the native <TT>G4ExcitationHandler</TT> for nuclear 
	    de-excitation after the cascade.</LI>
        <LI>The INCL light ion model now supports incident ions up to 18-Oxygen.</LI>
      </UL></LI>
  </UL></LI>

<LI>Nuclear de-excitation models have been improved to allow <TT>G4PhotoEvaporation</TT>
    to be used for nuclei with <TT>Z > 100</TT>.  Users may now include their own photo-evaporation
    data files.  Several improvements were also made to the Fermi-Breakup model to
    improve behavior for light (<TT>A < 17</TT>) target nuclei.</LI>

<LI>Several elastic scattering cross-sections, models and processes were extended to
    handle antimatter projectiles.  These include 
    <TT>G4WHadronElasticProcess</TT>, <TT>G4AntiNuclElastic</TT>
    and <TT>G4CHIPSElasticXS</TT>.</LI>

<LI>A new module which handles quasi-elastic scattering has been created.  It is
    extracted and now separate from the CHIPS code where it originated.
    It is used by all physics lists.</LI> 

<LI>Low energy neutrons interactions based on data-libraries:
  <UL>
    <LI>The Geant4 Neutron Data Library (G4NDL) is now based on the ENDF VII database
        exclusively.
        Its new version, G4NDL 4.0, is required for use with the High Precision (HP) 
        models with this release.</LI>
    <LI>New translations of alternative neutrons database (ENDF, JENDL, JEFF,
        MENDL, CENDL), are being made available separately from IAEA.
        These can be used with the current HP neutron models, for studies of systematics.</LI>
    <LI>Thermal scattering is enabled in the HP neutron models and the appropriate
        data files have been added to ENDF/B-VII, with the exception of para (ortho)
        H and D, liquid (solid) methane and benzene.</LI>
    <LI>New low energy neutron models (LEND) which use the Livermore neutron database
        have been released. They use the GIDI interface to the database.
        All information on this database will be maintained and updated by Lawrence
        Livermore National Lab.</LI>
  </UL>
</LI> 

<LI>Radioactive decay has been extended to handle forbidden beta decays and
    spontaneous fission.  The corresponding data set has been updated to
    reflect this.
    The radioactive decay code was also corrected to allow atomic relaxation of de-excited
    nuclei produced during alpha and beta decay.  Bug fixes in the internal conversion code
    now provide better agreement with deexcitation gamma spectra.  Also, new code and
    messenger commands now allow directional biasing of decay daughters, including e-, e+,
    gamma, n and alpha.</LI>

<LI>Improved muon-nuclear reactions are implemented in <TT>G4VDMuonNuclearModel</TT>.
    Here, the LEP models that used to handle the meson interactions are replaced by
    the Bertini Cascade.  A new cross-section class, <TT>G4KokoulinMuonNuclearXS</TT>,
    was developed which splits out the cross-section code which was formerly
    hard-coded into the old muon-nuclear process.</LI>
   
<LI>Energy and momentum checking at the process and model level can now be enabled
    by environment variable. </LI>
</UL>

<P> </P>
<B>Interfaces and Visualization</B>
<UL>
<LI>Improvements to the Qt Graphical User Interface and Viewer.
    Involves installation of Qt from qt.nokia.com and selection with CMake
    - see CMake instructions.</LI>

<LI>Users are encouraged to use the generic "<TT>/vis/open OGL</TT>" command,
    which selects the OpenGL viewer most appropriate to the
    installation.</LI>

<B>Physics Lists</B>
<UL>
<LI>The new <TT>G4SeltzerBergerModel</TT> bremsstrahlung model is used by 
    all standard EM builders below <TT>1 GeV</TT>.</LI>
<LI>The new <TT>G4UrbanMscModel95</TT> model is used by all EM builders
    except for <TT>G4EmStandardPhysics_option2</TT> in which the old 
    <TT>G4UrbanMscModel93</TT> model remains.
    In the <TT>G4EmStandardPhysics_option2</TT> builder, <TT>G4WentzelVIModel</TT>
    is used for multiple scattering of protons, pions and kaons.
    The Rayleigh scattering process is added to <TT>G4EmStandardPhysics_option3</TT>
    builder.</LI>
<LI>The physics-list factory allows to select one of EM options on top of base

<H2>5. Expected effects on physics and computing performance</H2>

<B>Standard Electromagnetic physics and cuts</B>
<UL>
<LI>Improved the accuracy of the Bremsstrahlung simulation and low-energy
    electron transport. Due to the adoption of the new model for Bremsstrahlung,
    the kernel part of the electromagnetic shower appears slightly narrower,
    no effect on the tails of the electromagnetic shower are observed.</LI> 
<LI>Retained similar CPU performance to the previous Geant4 versions.</LI> 
<LI></UL>

<B>Hadronic physics</B>
<UL>
<LI>The recommended physics lists for HEP applications (FTFP_BERT, QGSP_FTFP_BERT
    and QGSP_BERT), show results very similar to the previous production release.
    A small decrease in energy deposited in calorimeters is expected for FTF-based physics lists
    with respect to the previous release for primaries with energy above <TT>20 GeV</TT>. 
    The decrease is of order <TT>~1%</TT>.</LI>

<H2>7. Compilation Warnings</H2>

There may be a few compilation warnings on some platforms.
We do not believe that any of these lead to incorrect run-time behaviour.

<!-- ============================================== -->

<H2>8. Known Run-Time Warnings</H2>

The following message may be written to standard output at the end of a program:
<PRE>
    G4Transportation: Statistics for looping particles 
       Sum of energy of loopers killed: 
       Max energy of loopers killed: 
</PRE>
It provides the total energy (in <TT>MeV</TT>) of tracks  killed due to
excessive number of steps ('looping') during the simulation, and the maximum
energy of such a track. Such behaviour can be due to low-momentum particles 
which loop in magnetic fields (a physical effect, which can consume a lot of 
CPU time for little  ) 
or being abandoned due to being stuck at geometrical boundaries.
<P></P>
In case either of these reported energies is significant, we recommend
increasing the verbosity of <TT>G4Transportation</TT> to obtain information for
each track killed. A user can change the threshold energy above which particles
are killed more reluctantly (only after significant additional effort) using
the method <TT>SetThresholdImportantEnergy()</TT> of <TT>G4Transportation</TT>.
The default value is <TT>100 MeV</TT>.

<LI><B>Binary Cascade</B>
    <UL>
    <LI>Set E/p checking limits for energy non-conservation checks.
        Fixed large energy non-conservation for Hydrogen target (vector for the
        final state was not cleared before use). Also moved check for Hydrogen
        to <TT>ApplyYourSelf()</TT>.</LI>
    <LI><TT>G4GeneratorPrecompoundInterface</TT>: added code to calculate
        excitation energy as difference of initial-final state, to allow for
        energy conservation for string models. Reduced problem of energy
        non-conservation. Fix to add fragment nucleus to reaction products
        when no de-excitation. Replaced loop to decay input secondaries with
        new <TT>G4DecayKineticTracks</TT> utility. Fixed memory leak in to
        correctly delete kinetic track.</LI>
    <LI><TT>G4BinaryCascade</TT>: revised calculation of excitation energy
        when used for rescattering, removing systematic energy non-conservation.
        More changes/fixes for use with propagate interface.
        Added handling of detroyed nucleus, i.e. when charge becomes 0.
        Some code cleanup, mostly <TT>ApplyCollision()</TT>.</LI>
    <LI>Fixed bug in <TT>G4RKFieldIntegrator</TT>, following Xcode warning.</LI>
    </UL></LI>
<LI><B>Bertini Cascade</B>
    <UL>
    <LI>Developed infrastructure to support using Bertini as a "rescattering"
        model for the output of the FTF simulation.</LI>
    <LI>Make cross-section tables self-registering at job initialization.</LI>
    <LI><TT>G4NucleiModel</TT>: added optional
        argument to <TT>reset()</TT> with list of collision points, for
        copying cascade state when rescattering. Optimised computation of
        "rho". Reverted length scales to "2.82" factor. Compared local
        kaon/hyperon cross-section tables with sum-of-exclusive tables
        from <TT>G4Cascade*Channel</TT> classes.
        Fixed bug in <TT>G4InuclNuclei</TT> constructor (mom,A,Z,Eexc,model)
        to properly set excitation energy; caused energy non-conservation in
        de-excitation code. Changed kaon potential to be positive, not
        negative, so slow kaons will occasionally be captured.
        Removed obsolete local cross-section arrays;
        use standard tables, which are numerically equivalent.</LI>
    <LI><TT>G4CascadeInterface</TT>: added support for capturing random-engine
        state for debug at each <TT>ApplyYourself()</TT> or <TT>Propagate()</TT>
        invocation. Simplified <TT>NoInteraction()</TT> to
        have no particles returned, but use <TT>SetEnergyChange()</TT> to
        communicate to tracking that real track should be stopped and deposit
        all its energy. Only projectile is copied to final state, not target
        nucleus. If accept/reject loop fails (maximum retries), return initial
        state untouched rather than last generated cascade. This avoids
        exposing an elastic scattering event under any circumstances.
        Use new <TT>G4DecayKineticTracks</TT> in <TT>Propagate()</TT> to
        handle short-lived inputs. Set up for E/p checking by
        <TT>G4HadronicProcess</TT> in constructor; set internal E/p limits
        (currently 5% and <TT>10 MeV</TT>).</LI>
    <LI>Simplified cascade test-and-repeat loops; do four-momentum balancing
        with nuclear fragment, now used exclusively as <TT>G4Fragment</TT>,
        at end of cascade, not after de-excitation.</LI>
    <LI><TT>G4CascadeCheckBalance</TT>: added non-limit ctor and explicit
        limit setting.</LI>
    <LI><TT>G4IntraNucleiCascader</TT>: added list of hit-nucleon locations,
        filled by <TT>copyWoundedNucleus()</TT> for initialization of
        <TT>G4NucleiModel</TT>. Reduced number of retries from 1000 to 100.
        For pre-cascade rescattering, put
        resonances, or any particle which cannot be propagated by Bertini,
        directly onto output, without decaying.</LI>
    <LI><TT>G4CollisionOutput</TT>: added non-const accessors for lists.</LI>
    <LI><TT>G4LorentzConvertor</TT>: added diagnostic messages in <TT>rotate()</TT>.
        Drop most "intermediate" kinematic parameters used in rotate,
        in favor of somewhat more direct vector operations.</LI>
    <LI><TT>G4CascadeChannelTables</TT>: use <TT>FindTable()</TT> to determine
        if table has been created already or not. Added new gamma-nucleon
        interaction states.</LI>
    <LI><TT>G4CascadeGamNChannel, G4CascadeGamPChannel</TT>: new final state
        tables for gamma-nucleon interactions, with final states up to 9-body,
        using the same energy binning as pion-nucleon.</LI>
    <LI><TT>G4Cascade*Channel</TT>: added new constructor argument for all
        cross-section tables. Removed all namespace self-instantiations
        to fix incosistencies in initialization across platforms.</LI>
    <LI><TT>G4Inucl*Particle</TT>: modified all constructors to take the model
        code as an optional argument, so that subclasses don't have to set it
        manually.</LI>
    <LI>Fix in <TT>G4ElementaryParticleCollider</TT> to hide no longer used
        "mult" argument to <TT>getMomModule2toMany()</TT>; removed special
        "mult==3" case.</LI>
    <LI>Fix in <TT>G4CascadeT1NNChannel</TT> to final 9-body final-state list
        for both nn and pp: existing entries violate charge.</LI>
    <LI>Added protections in <TT>G4LorentzConvertor</TT> for <TT>rotate()</TT>
        applied to at-rest system (i.e., <TT>z-axis ~ (0,0,0)</TT>), and
        simplified calculations.</LI>
    <LI>Updated to reduce memory churn in <TT>G4IntraNucleiCascader,
        G4FissionStore, G4Fissioner, G4CascadeInterface,
        G4InuclElementaryParticle, G4BigBanger, G4ElementaryParticleCollider</TT>.</LI>
    <LI><TT>G4EquilibriumEvaporator</TT>: improved building of final-state
        particles to reduce creation of temporaries.</LI>
    <LI><TT>G4CollisionOutput</TT>: use <TT>resize()</TT> and set/fill to
        eliminate temporary copies. Added diagnostics and fixed bug with
        momentum units.</LI>
    <LI><TT>G4CascadParticle</TT>: added functions to explicitly set all data
        members, including initial path and generation, to support changes
        below. Re-order member functions in set/get pairs.
        In <TT>getPathToTheNextZone()</TT>, check
        for zero momentum (<TT>pp < 1e-9</TT>) and return zero path-length;
        this will support capture at rest.</LI>
    <LI><TT>G4CascadeCoalescence</TT>: NEW factory class to implement
        conversion of final-state nucleon "clusters" into light ions.
